This is the most powerful incarnation of Magneto, which is probably when he set off the worldwide EMP wave in the classic Fatal Attractions storyline. Mags can also do stuff like control blood flow to the brain and effect iron in people's bloodstream, can he not? I think that Mags can take this one. Speaking of, did the two of them encounter each other during World War Hulk? Or was Mags not part of the X-team back then? Thanks. Happy Holidays.
